Bromine azide is a chemical compound from the group of azides or nitrogen halides .

Extraction and presentation

Bromine azide, by reaction of bromine with sodium azide or hydrogen azide or silver azide are obtained.

properties

Bromine azide is a colorless explosive liquid. The condensation of gaseous bromine azide to an orange-red liquid usually leads to an explosion. The pure liquid decomposes easily and is soluble in water to form a brown solution.

{\ displaystyle {\ ce {BrN3 + H2O -> HBrO + HN3}}}

The bromine azide molecule is in a trans -configuration with weakly angled N ₃ unit and having a sp ² - hybridization bearing Br at the N-atom matching Br-NN-angle. In contrast to the chain-like iodine azide , bromine azide has a helical solid-state structure.

use

Bromazid and alkenes provide vicinal azido-bromo-alkanes. Addition to styrene in polar solvents gives 1-azido-2-bromo-1-phenylethane with 95% yield.
